Safety instructions
2.1 Residual risks
PM250 Power Module
Hardware Installation Manual, 09/2012, A5E01003502B AD
17
– Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
– Response times of the controller and drive
– Operating and/or ambient conditions outside of the specification
– Condensation / conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of radio devices / cellular phones in the immediate vicinity of the controller
– External influences / damage
2. In the event of a fault, exceptionally high temperatures, including an open fire, as well as
emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,
e.g.:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions outside of the specification
– External influences / damage
Inverters of the Open Type / IP20 degree of protection must be installed in a metal
enc
losure (or protected by another equivalent measure) in such a way that the contact with
fire inside and outsid
e the inverter is prevented.
3. Hazardous shock voltages caused by, for example:
– Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operating and/or ambient conditions outside of the specification
– Condensation / conductive contamination
– External influences / damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
close.
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly.
Note
The components must be protected against conductive contamination (e.g. by installing them
in a cabinet with degree of protection IP54B to EN 60529).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.
For more information about residual risks of the components in a power drive system, see
the relevant chapters in the technical user documentation.
